BURNER. FOR COAL-OIL LAMPS.

Specification forming part of Letters Patent No. 39,856, dated September 8, 1863; antcdated May 13, 1863.

To all whom it may concern Be it known that I, ANNA O. VVILHELM, wife of Charles W'ilhelm, oi" the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Burners for Goal-Oil Lamps; and I do hereby declare that the tol:owiug is a full, clear, and exact description of the construction and operation of the same, reference being bad to the accompanying'drawings, making a partof this specification, in which- Figure 1 is a perspective view ot' the same, and Figs. 2 and 3 vertical central sections at right angles to each other, like letters in the ditt'erent figures indicating the same parts.

The object of this invention is the produc tion of a burner for coal-oil lamps without a chimney, that will serve in a more effective and reliable manner in producing a bright light without smoke, and also in preventing an extinguishment ot' the flame by currents of air, in carrying the lamp about.

It consists in surrounding the Wick-tube by a hollow tapering jacket, constructed and applied substantially as hereinafter described and specified, so as to'prevent all access of currents of air to the sides of the wick-tube, tend to direct the immediately-surrounding air-in upward currents to support the combustion, and also serve to protect the thin side edges of the flame at the wick from being extinguished by lateral currents of air.

In the drawings, A is the jacket, B the wick-tube, and O the supporting-base, where by the whole is secured to the bowl of a lamp. The wick-tube in this instance is made flat throughout, extends upward from the base 0 about two inches, (more or less,) and is provided with the usual well-known wick adj usting device I), as seen in Fig. 1.

The jacket A is constructed of thin plate metal, in the form shown in the drawings-i. 0., with its lower end sutficiently large in its diameter to fill the usual depression, c,in the base from which the wick tube B rises, while its upper end is flattened so as to make it fit closely around the upper orifice of the said Wick-tube, a small slot, at, being out in its lower end to receive the stem of the wickailjuster b, so as to allow of the removal and replacement of the said jacket A, as occasion may require. The upper end of the jacket A is provided with two guards, a a each of which projects about a quarter of an inch above the said upper end, and when'thejacket' is applied above the upper end of the wicktube B, as seen in Fig. 1.

It will be seen that thejacket A produces aroomy chamber around the wick-tube P, while its exterior slopes gradually upward on two sides into contact with each of the two broader sides of the upper end of the wicktube, the two flame-guards a a being in contact with and projecting above the two narrower sides of the same, as seen in the draw ings.

in operation thejacketA serves to produce a capacious chamber around the lengthy wicktube, B, and thus prepares the oil absorbed by the wick for a more ready combustion as it reaches the upper end of the latter, while the sloping, broad sides of the said jacket give an upward tendency or direction to the air coming into contact with the flame, thus ett'ecting the combustion of the oil in a more favorable manner for producing a smokeless light. The guards a a protect, in an effective manner, the two thinner, and therefore more easily extinguishable, portions of the flame against currents of air produced by carrying the ignited lamp about, or otherwise.
